Charles H. Spurgeon on Psalms 78:25

The more excellent the benefit is which God giveth, the greater is the ingratitude of him who doth not esteem of it and make use of it as becometh; as we see in Israel's sin, who did not esteem of manna as they should have done. Had the Lord fed them with dust of earth, or roots of grass, or any other mean thing, they should have had no reason to complain: but when he giveth them a new food, created every morning for their sakes, sent down from heaven as fresh furniture every day, of such excellent colour, taste, smell and wholesomeness; what a provocation of God was it, not to be content now; in special, when he gave them abundantly of it? He sent them meat to the full. David Dickson.
